Daughter card assembly having a power contact

A receptacle connector comprising:

• a connector housing having opposite mating and loading faces and a mating axis extending therebetween, the connector housing having a card cavity that is accessed through the mating face and an interior wall that extends along the mating axis defining the card cavity, the connector housing and the card cavity extending lengthwise along a longitudinal axis that is perpendicular to the mating axis;
• signal contacts arranged along the interior wall and exposed to the card cavity;
• and
• a power contact disposed within the card cavity, the signal contacts and the power contact having different cross-sectional dimensions;
• wherein the power contact and the signal contacts have respective wipe surfaces that engage corresponding electrical contacts of a daughter card during a mating operation, the daughter card coinciding with a central card plane when the daughter card and the receptacle connector are mated, the wipe surface of the power contact being a first center distance away from the card plane, the wipe surfaces of the signal contacts being a second center distance away from the card plane, the first center distance being greater than the second center distance.

A communication system comprising:

• a receptacle connector comprising a connector housing having opposite mating and loading faces and a mating axis extending therebetween, the connector housing having a card cavity that is accessed through the mating face, the receptacle connector including signal contacts and a power contact disposed within the card cavity;
• and
• a daughter card assembly configured to mate with the receptacle connector, the daughter card assembly comprising:
• a daughter card having a leading edge extending along a longitudinal axis, the daughter card including first electrical contacts that are disposed along the leading edge;
• and
• a power module coupled to the daughter card proximate to the leading edge, the power module including a module housing having a module cavity and a cavity opening that provides access to the module cavity, the power module also including a second electrical contact that is disposed within the module cavity and projects through the cavity opening;
• wherein the signal contacts of the receptacle connector engage the first electrical contacts of the daughter card during a mating operation and the power contact of the receptacle connector engages the second electrical contact of the daughter card during the mating operation, the second electrical contact being deflected toward the daughter card by the power contact as the second electrical contact and the power contact engage each other.
